[Question from NMRWiki Q&A forum] How to extract residue information in case of line broadening (intensity drop ) of HSQC titration of protein - protein interaction data ?
How to extract residue information in case of line broadening (intensity drop ) of HSQC titration of protein - protein interaction data ?
Dear Friends
we have done HSQC gradient titration with targeted proteins , most of cross peaks we observed intensity drop , 30 out of 95 peaks ( 70 percent intensity drop of each cross peak ) , other cross peaks also we observe intensity drop less than 70 percent , we did n"t observe any chemical shift change .( May be it is due to intermediate exchange regime of complex ) .ITC experiment showing 12uM binding constant .AUC experiment result is...

Nearly all the macromolecular three-dimensional structures deposited in Protein Data Bank were determined by either crystallographic (X-ray) or Nuclear Magnetic Resonance (NMR) spectroscopic methods. This paper reports a systematic comparison of the crystallographic and NMR results deposited in...

SUMMARY: We cast the problem of identifying protein-protein interfaces, using only unassigned NMR spectra, into a geometric clustering problem. Identifying protein-protein interfaces is critical to understanding inter- and intra-cellular communication, and NMR allows the study of...
